170 all whom/it may concern:

Be it known that I, DAVID 0. SWEET, a resident of the city ofProvidence, in the county of Providence and St-ateof Rhode Island, haveinvented certain new and useful Improvements in Machineslfor Twistingand Spinning Fibrous Materials; and I do-hereby declare that thefollowing is a full, clear, .and exact description thereof, referencebeing had to .the accompanying drawin s, and to the characters ofreference: marke thereon,

which form a part of this specification.

,This invention relates tospinning-ririgsf and has for its object theproduction of a simple-and effective ring for. increasing the" capacityof the spinning-frame and is designed for application to spinning andtwisting frames and the like. p

My device is designed to facilitate'spinning andtwisting by providing animproved substitute for the'fliers, rin s, andtravelers and the likedeviceshereto ore em loyed' in spinning and twisting frames and t elike.

The invention consists in animproved construction of a rotating ring andwhirl con1- bined, carryinga thread-guide and supported from itsinternal surface on bearin s both above and below the point-where theband engages said whirl. The bearings for this combined whirl and ringare located within an annular shell or case especially designed toinclose the same and to receive and retain any stray articles oflubricant which may have worke from the contact-surfaces. It is awell-known fact that revolving spinnin -rings on account of theirhigh-run ning ve ocity re uire almost constant lubrication, which lurication is ofvital importance t0. the successful operation of the de-,vice. To accomplish this, many methods have been tried of submeriilrggsome of the runningpartsinoil andint' or forcing the oil to thebearing-surfaces but where this is done it is found absolutelyimpossible in the practical operation of the ring to confine this .oilso it will not be thrown upon the thread or yarn by the centrifu al Toobviate this diflioulty, I have constructed a reservoir for thereception of the lubricant,

-Which reservoir isindependent from the ring,

and remove the lubricant far enough from the revolving parts, so thatthe centrifugal force or air-currents enerated by such parts Wlll notact on said lubricant to scatter it. I

have also arranged to draw said lubricantfrom the reservoir and supplyit direct tothe running parts in quantities just sufficient tothoroughly lubricate such parts, leaving none to be thrown ofi.

The invention consists of other novel features and parts andcombinations of the same, as will be fully described hereinafter andthen pointed out in t e appended claims. A practical embodim nt of theinvention is represented in the accompanying draw-- mgs, forming a partof this s ecification, in

which similar 'charactersof re erence indicate corresponding parts inall theviews.

Fig; 7 -isa central longitu- F g. 8 is a plan view of a portionofsaidrail';

which IZhave shown as made'hollow to serve asza reservoirto hold oil orother lubricant which maybe su plied to the revolving rings that, aremounte on said rails in the manner hereinafter described. Theconstruction of this rail is best'shown in Figs. 7 and 8,

which it-is represented in the form of a trough having sides 2 2 and abottom 3. Progecting upward at intervals from the'bottom of this railare bosses 4 4 forsu iporting'lthe spinningosses- 1 rings, each of whichp threaded center portion. At-5 is a c or plate that covers the trough,said plate av. mg holes 6 6 through it for the reception' of the rings.At 7 inthis rail is-an overflowpassage for regulating the .depth or theamount of oil the reservoir can hold. When as a hollow the oil is ouredinto this rail-,it rises until it reaches t e. bottom of this passage 7,when if more is poured in it runs out throughthis opening. The object ofthis construction is to effectually prevent a careless operator fromfilling the reservoir so that the oil could come in contact with or beefle'cted by the revolving parts.

At 8 is a etcock for drawing off the oil when desired The rotatablespinning-rim 9 is formed into an elongated annular she I or case, havinga groove 10 around its middle portion for the reception of thedriving-band. (Not shown.) Where the groove 10 in this ring comes, it isreinforced on its interior wall, forming shoulders or bearings 11 and12, where the balls 1 3 may track. The inner walls of the ring at 14 and15, both above and below the shouldersQare beveled inwardly as theyextend out from said shoulders toward the ends' of the ring. The objectof these beveled walls is to prevent the oil from climbing up the samewhen the ring is revolvin rapid y, the tendency being always for the oito get as far from the center as possible. In this manner the oil isretained in the pockets right where the ball finds two of its bearingsOn both the upper andlower edges of this ring are shown narrow annularflanges 16 and 17, which are designed as a further preventive for theescape of oil; but it is found in practice that these are not necessaryfor this purpose. On the upper end of this ring is the thread-guide 18,which is made u in the form of a thin band inclined inward y at 19 atits upper edge and has projecting from this edge a plurality of hooks orguides 20 20 to engage and carry the thread. On the lower edge of thisband is a T-shaped slot 21,

that sets over pins 22 22 in the upper edge of the ring 9, and by aslight turn each pin enters one of the wings of the slot, and thethread-guide is securely locked in position to said ring.

At 23 is a tubular portion that forms the fixed inner wall and throughwhich the bobbin is designed to pass. This tube has anoutwardly-extendin flan e or head 24 on its upper edge, under w ich angeis secured the hardened; beveled, or cone-faced ring, servmg as-an upperbearing, against which the uper-set of balls 13 runs. This ring may behe din place by the screws 25 25 through the flanged head of the tube 23or in any other suitable manner. At 23 is the check-nut, that retainsthe said tube firmly in position in I the rail.

I A second hardened cone-bearing ported on the upper en serves as thelower bearing. for the lower set of balls 27. This ring. is looselyheld'to the tube by the key 28 iii-the said tube, that enters thecorrespondin slot 29 in said ring.

The lower portlon of t is tube 23 is threaded at 30 and lsscrewed intothe boss 4 in the rail, and by setting thls tube either up or down thebearings may be adjusted and the wear of the running parts taken up. 4

The oil is carried from the reservoir below by capillary attraction upto both the upper and lower ball-bearings through a wick'31.

but a flat wick is used in practice with equally good results. In orderto carry said wick up the side of the tube, it must be passed throughthe slotted portion 32 in the lower conebearing, which slot is made insaid ring for that purpose. It may then be extended up through a similarslot in the up er ring and hung from the top of the same own toward therevolving balls. It will be observed that by this method the oil isapplied to the balls at their innermost points, sothat by centrifugalforce the lubricant will spread itself all over the same in a thin filmand will naturally be carried to all of its three bearing-points.

As the oil is feed very slowly, not enough ever accumulates to fill thepockets in the case, and no oil can possibly et out from the inside ofthe ring when thus constructed to spoil the yarn or thread.

I have shown the rail as forming the oilreservoir; but I do not wish toconfine myself to this construction, as the reservoir may be constructedof any material and placed at any convenient point. Any reservoir thatis independent and removed from the revolving parts, with means forcommunicating from said reservoir to such parts, comes within the spiritand scope of my invention.

The above-described construction provides perfect lubrication-to theinclosed running parts and at the same time positively obviates thethrowing of oil, which difliculty has heretofore proven fatal to therunning of r0- tary spinning-rings at a high velocity.

This revolving ring and whirl, as stated above, "runs at a greatvelocity. Therefore it is very essential and desirable to reduce to aminimum degree the extent of the. friction With this end in view I haveplaced the supporting-bearings of the ring and whirl on the interior ofsaid ring and 1 as near to its center as possible, thus obtain- 26 issup-i d of the bosses 1' and.

bearing-surface.

ing a considerable advantage in practical construction over theold form,where the bearroe ring is reduced to a minimum by my metlmd" ofsupporting said ringfboth above and beiew the point where the strain isapplied. The
